TABLE.

Application filed April 6,

My invention relates to extension type of tables, the object being toprovide means whereby the extension leaf may be stored within the tableas an integral unit Without hinging or folding the same, and whereby itis caused to assume its proper place as a part of the table top by theextending of the table.

I accomplish this object by means of the construction illustrated in theaccompanying drawing, Which is a part of this application for LettersPatent, like characters of reference indicating like parts throughoutthe several. vievvs thereof, and in Which Fig. 1 is a transverse sectionof the table top in closed position.

Fig. 2 is a similar view With the table top partially open.

Fig. 3 is a. similar View With the table top further opened.

Fig. 4 is a similar View with the table top fully opened, and theextension leaf in position.

Fig. 5 is a longitudinal section of the table top with the extensionleaf in stored position therein.

Fig. 6 is a section upon line 6 6 of Fig. 5.

Fig. 7 is an end elevation of the table top with the extension leaf instored position.

The table top is of the ordinary construction, having separable topmembers 8 and 9 with aprons 10. At each end of the table are a pair ofcoacting guide slides, the outer of each pair of slides, 11, beingsecured to the top member 8, and the inner slide of each pair, 12, beingsecured to the top member 9. These slide guides operate in a guidemember 13, as shown in Fig. 5, and the. guide members 113 are connectedby a cross piece 14 to which the legs 15 are secured. By thisconstruction I eliminate all top supporting members and slides from thecentral portion of the table.

The upper surface of each ofthe guides 11 and 12 is notched to receivethe extension leaf 16, which lies in said notches beneath the table topWhen it is not in use. When the leaf 16 is in stored position one end ofthe notch in the guide slides 11 contacts with the leaf, as shown at 11ain Fig. 1', While the opposite end of said notch is upwardly inclinedfrom a point 11b spaced some distance from the leaf 16. That end of thenotch in slide 12 adjacent the inclined portion just described contactsWith the leaf 16 as at 12a in Fig. 1, and the opposite end of the notch1926. Serial No. 100,084.

When th-e leaf is in the position shown in Fig. 3 it is necessary toraise it out of the notches in the slides 11 and 12 into position suchthat the top members 8 and 9 may be closed upon the leaf. This Iaccomplish by providing a shaft 17 journaled in the slide members 12 andhaving lcams 18 secured thereupon adapted to lift the leaf into itsuppermost position, as shown in Fig. 4. To operate said shaft and cams Iprovide an arm 19 secured to the shaft, and a rod 2O passing from saidarm through one of the aprons 10 yand terminating in a suitable handle21. lNhen not in use the cams 18 lie beneath the stored leaf as shown inFigs. 1, 2, 3 and. When it is desired'to raise the leaf into itsuppermost position a pull upon the handle 21 rotates the shaft 17 andthe cams 18 into the position shown in Fig. 4, and thus raises the leaffrom the position shown in F ig. 3 into the position shown in Fig. 4. inwhich latter position it is ready to have the top members 8 and 9 closedupon it.

With this construction of table it is necessary that the top members 8and 9 should move equally from the center of the table as they areseparated. This mayv be accomplished in many Ways, that found convenientin materializing my invention is a right and left hand threaded screw 22mounted in a bearing 23 secured to the cross piece 14, and heldlongitudinally therein by collars 24, as shown in Fig. 6. Secured to thetop members 8 and 9 are threaded brackets 25 and 26 adapted to receivesaid threaded screw, and the screw extends through one of the aprons 10to terminate in a handle 27 for operating the same, as shown in Fig. 6.

My invention may be made of any size and constructed of any materialsdeemed convenient and suitable for a device of this character, and WhileI have illustrated and described a form of construction found desirablein materializing my invention, I Wish to include in this application allmechanical equivalents and substitutes that may fairly be considered tocome within the scope and purview of my invention as defined in the appended claim.

Having disclosed my invention so that others may be enabled to constructand to use the same, what I claim as new, and desire to secure byLetters Patent is In a table: movableptop members; an eX- tension leafpositioned beneath said top mem* hers to guide the same in theirrelative movement as the table is extended when not in use; coactingslides for said members; coact# ing notches in said slides to receivesaid leaf and adapted to raise the leaf when said slides are operated; ashaft journaled in said slides; a cam upon said shaft adapted toposition the raised leaf intermediate said top members; a lever uponsaid shaft; and a rod connected to said lever for operating said shaft.

In witness whereof I claim the foregoing as my own I hereunto aiix mysignature at Portland, county of Multnomah, State of Oregon, this 1stday of April 1926.
